It was revealed earlier this month that Varada Sethu will officially be joining the series as the Doctor's second companion in season 15, with the three set to be quite the dream team.

Well, it turns out that things are simply "hot" with another companion in the mix, according to series stars Ncuti Gatwa and Millie Gibson, who spoke to RadioTimes.com on the blue carpet for the season 14 premiere.

Doctor Who will return on Saturday 11th May on BBC iPlayer and BBC One.
